On my Dedicated BI machine at the Condo I'm running a Samsung Evo 256GB SSD, and an 8TB WD84PURZ, 3.5"/128 MB/5640 RPM and a 5TB 3.5" WD50EZRZ 5400 RPM.
Im leaving about 300-500 GB free space on each WD drive.
Cam 19 went online yesterday. About 2/3rds of the cams are written to the Surveillance drive in the folders NEW Aux1 Aux2 Aux 3 Aux 4 Aux 5 Aux 6 Aux 7 Aux 8 Aux 9.
And about 1/3 are written to the 5TB WD white label drive in folders named Aux 10,11,12,13
Stored is not used. I'm getting 5-6 weeks on average for storage.
If a I see a suspicious vehicle Casing the parking lots, I create a folder in the Pictures folder named with the License plate.
Or if a resident is doing suspicious shit, I create a folder named like Unit119. every dumb ass thing they do goes into the folder.
